GEORGE E. BLOOD, OF N'UNDA, NEW YORK, ASSIGNOR TO FOUTE COMPANY, OFNUNDA, NEW YORK, A CORPORATION OF NEW YORK.

LOADING SKIP FOR CONCRETE PAVERS.

Application filed November 19, 1923.

To @ZZ whom t may concern:

Be it known that I, GEORGE E. BLOOD, a citizen of the United States ofAmerica, residing at Nunda, in the county of Livingston and State of NewYork, have invented certain new and useful Improvements in Loading Skipsfor Concrete Pavers, of which the following is a specification.

My invention relates to new and useful improvements in loading skips forconcrete pavers, and particularly to the manner in which the skip ismounted on the paver.

One of the principal objects of the invention is to provide a loadingskip having a double pivoted action, permitting the bottom of the skipto swing in a short arc thereby causing the materials to start flowingfrom the skip much more quickly than they ordinarily do when the skiphas but a single pivot point and is elevated in a long arc.

Still another object of the invention is to provide a skip which isrigidly supported at two points, one point of support being near themouth, and the other near the center of the skip bottom; these twopoints of support extending transversely of the bottom of the skip,thereby rigidly holding the skip in its path of movement and preventingthe usual side sway.

Still another object of the invention' is to provide a skip and a meansfor mounting the same, so that the mouth of the skip passes over the topedges of the hopper by the time the skip back reaches a horizontalposition, thereby eliminating all chance for any of the material tospill outside the hopper' Still another object of the invention is to somount a skip that it will be elevated through a short arc, so that thelift is more nearly to the perpendicular, thus avoiding semi No.675,611.

to provide a skip having two sets of supporting arms of differentlengths and eccentrically mounted so that an initial lifting movement ofthe skip will draw the mouth of the skip inwardly towards the hopper ofthe paver.

Still another object of the invention is to provide a skip wherein thesupporting arms may be quickly and readily secured to the skip andquickly mounted on the paver and after having been operatively secured,will need no further attention; and at the same time, will alwaysprevent any side sway or lost motion during its travel.

Still another object of the invention is to provide a skip which will beeconomical in its construction and operation, and relai tively cheap tomanufact-ure.

With these and numerous other objects in view, the invention consists incertain new and novel arrangements and combinations of parts, as will behereinafter more fully described and pointed out in the claims.

Referring now to the drawings,

Fig. l is a perspective showing the skip and the manner in which it ismounted to the paver, the skipbeing shown in its lowermost position.

F ig. 2 is a similar View showing the skip, in this instance, in itsuppermost or dumpl ing position.

Fig. 3 is a reduced diagrammatic view of the skip showing the arcs oftravel in dotted lines, the skip being in its lowermost position.

Fig. 4 is a similar View, the skip being shown as partly elevated, and

Fig. 5 is a similar view, the skip being shown in its uppermost ordumping position.

Referring now to the several figures, there is shown one type of a Footepaver con sisting of a platform l, the endless track 2, the usual drum3, a skip t, the cable 5 for raising the skip, and the support 6 for thecable. rllhe hopper 7 is also shown for the drum, as well as numerousother parts, but I have not shown any of the discharging apparatus ofthe paver, such as the boom, bucket, or the trough, etc.

Referring now more particularly to the skip a, it will be seen that itconsists of a relatively short back 8, the side walls 9, and

lilf) the bottom 10, the side walls of both the back and the bottommerging and riveted along the lines shown. A cover 11 is shown abovethemouth of the skip extending rear-l wardly so that the materials inthe skip will not overflow the side walls near the mouth. lt will heseen that the bottom of the skip extends at an obtuse angle to the back,and the greatest depth of the side walls is diagonally opposite themerger of the back and the bottom. A reinforcing angle iron 12 extendsacross the back and side walls to add'rigidity to the whole, while asuitable central b race 13 is shown to which the cable 5 is. attached;this cable passing over the Sheave liat the top of the support G andmeans, of course, are present to actuate the cable and raise and lowerthe skip.

Referring now more particularly to Fig. there will be seen a short baror plate 15 which isl located transversely of the bottom of the skip andat a point near the center thereof. At the opposite ends of this plate15 are two bearings 16 forthe pivotal. reception. of the long supportingarms 17 which are likewise pivoted at their lower ends of the rod 18,which in turn, is suitably mounted in the bearings 19. A second similarplate 2O is shown, somewhat shorter in length, this being fastened tothe bottom 10 of the skip and atl but a short distance from the end ormouth ofl the skip. This plate also has the bearings 21 at its oppositeends, in which are pivoted the upper ends ofy the short arms 22, whiletheir opposite ends 22 are pivotally mounted on the rod 23 which.

likewise, in turn, is mounted inthe bearings 24 on the superstructure ofthe paver. Extending between the two arms 22 and pivoted thereto is theplate 25, and also the angles 26., these members greatly strengthening,the supportk as a whole and giving the armsthenecessary rigidity. Byglancing at the diagrammatic Figures 3, 4L and 5,;it will be seen thatthe mouth of the skips and the upper pivotal point of the shortarms 22travel in the arc asv outlined by the dotted lines 27, while the nearlycentral portion of the back of the skip and the pivotal point of thearms 17, travel in the larger arc 28.

From Fig. 4 it will be seen that after the skip has reached` av positionnearly midway of its, travel, the mouth of the skip will be nearly overlthe hopper 7 and by the time the backl of the skiplhas reached aperpendicular position, the mouth will be directly over-the hopper 7.rllhis is an advantage as it prevents any, loss of material from the`mouth of the skip, as is often the case with the ordinary typeof skipsnow in use. The position-of the skip when ithas reached its uppermostposition of travel is clearly shown in Fig. 5, the lower arms now beingin a verticalor an upright position, the other arms having moved alongthe dotted lines 28 and extending substantially parallel with the bottomof the skip.

By glancing at these three figures (Figs. 3, l and 5), it will be seenthat the pull on cable 5, to start with, will cause the skip to elevate,the mouth of the skip starting directly upwardly and `inwardly while thenearly central portion of the back of the skip terials to start to,vflow from the skip much c more quickly than were they skip. elevatedfrom a single pivotal point, and moved through a long arc.

By pivoting the long'y arms 17 and the short arms 22, respectively, toplates which extend across the bottom of the skip, the skip will beelevated and travely through. its path of movement without tiltingtowards its opposite side or in` other'.v words, will be rigidlysupported and held from. side sway which often causes the material tosplash from the sides of the skip. l

From the foregoing it will be seen that numerous advantages areobtained, by providing two sets of supports, one set of whichl will belonger thany the other, and. whereint their inner pivotal points areeccentrically arranged. The skip may be elevated` more quickly than theusualitype of skip now inuse, and the material will also start flowingmore quickly from the skip-while the vmouth of the skipl will travelslightly upwardly.l and inwardly at its initial movement towardsthe highhopper and will reach it before the relatively short back assumes averticalposition. The skip and ,the supporting, parts may be readilyassembled, are relatively cheap to manufacture` andv have proved highlyeliicient .and economical .inl operation.

Many slight changes might-.be madef with.- out in anyway departing from`the spirit and scope of my invention.

Having thus described the same, what lv claim as new anddesire to secureby Lettersl Patent is 1. In a concrete paver having a rotatable mixingdrum, a loading skip for charging said drum, pivotal sets of arms forguiding and supporting said skip in its movement, a brace extendingacross one set of arms, bo-th sets of arms being eccentricallv mountedto the paver'at their inner ends and pivotally mounted near the mouthandr center of the back of the skip respectively so that a movementofthe skip will cause the mouth and the central portion thereof to movethrough arcs of eccentric circles.

A concrete paver comprising in part a rotatable mixing drum, a loadingskip for charging said drum comprising a back and bottom substantiallyat right angles to each other, arms pivotally secured near the mouth ofsaid skip, further pivotal arms of greater length secured near thecenter of the bottom of the skip, and each set of arms having separateinner aires so that the back of the skip tips with relation to the mouthwhile the skip is being elevated and the mouth of the skip approachingthe drum during its upward travel.

3. A loading skip comprising a back and bottom extending atsubstantially right angles to each other adapted to be secured to aconcrete paver, a plurality of supporting means pivotally mounted. tosaid skip and the inner ends of said supporting means beingeccentrically mounted on the paver, the inner pivotal points being sopositioned that an initial upward movement of the skin will cause themouth thereof to move upwardly and inwardly, and the remainder of theskip to move upwardly and slightly Ioutwardly, while a continuedmovement of the skip will cause the remainder of the skip to moveupwardly and inwardly to thereby discharge the contents.

4. In a concrete paver having a rotatable drum and hopper for the same,a loading skip the bottom and back of which extend at an obtuse angle toeach other for charging said drum, means for supporting said skipcomprising two sets of pivotal arms eccentrically mounted with relationto each other at their one end to the paver, one set of arms beingpivotally secured at their outer ends to the skip and near its mouth,and the other set of arms being pivotally secured to the bottom of theskip near the center, the length of said arms and the position of theircentral axes being such that when the back of the skip is in an uprightposition, the mouth of the skip will be over the hopper and the bottomof the skip will rest on and be supported by the set of arms securednear the center yof the bottom.

5. A concrete paver comprising in part a rotatable drum having a hoppertherefor, a loading skip for charging the drum, two sets of supportingarms pivotally secured to the skip at their one end, and pivotallysecured to the paver at their opposite ends, the two sets of supportingarms being of different lengths and having eccentrically positioned axesso that when the skip is elevated, the mouth of the skip will be overthe hopper when the bottom of the skip is in horizontal position and acontinued movement from this point causing the material to flow into thehopper, the longer set of arms being so arranged that when the skip isin its upright position, substantially onehalf of the bottom rests ouand is supported by these arms.

6. A. concrete paver comprising in part a rotatable drum, a hopper forthe drum. a loading skip comprising a back and bottom extending at anobtuse angle to carl; other for charging the drum, a pair of armspivotally mounted to the paver beneath the hopper and also pivotallymounted to the bottom of the skip near its center, a second pair of armsof shorter length than the first mentioned arms pivotally connected tothe paver and the pivotal point being below that of the inner pivotalpoint of the first mentioned arms, and at a distance further removedfrom the hopper, the outer ends of said last mentioned pivotal armssecured to the skip and near the mouth thereof whereby from the initialmovement as the skip is elevated, the double pivotal action will causethe mouth of the skip to swing inwardly as the remainder of the skip iselevated and to cause the material to discharge when the bottom of theskip is in a plane higher than the mouth.

7. A loading skip for concrete pavers comprising a back, a bottom andmerging side walls, pivotal arms secured to the bottom of the skip, asecond set of pivotal supportino arms mounted on the bottom of the skipanc near the mouth thereof, the said arms being of different lengths andadapted to be eccentrically mounted on the paver so an upward movementof the skip will cause the mouth to swing upwardly and the skip to tiltforwardly and the first set of arms so arranged to support the skipalong its bottom and prevent a side swaying movement when the skipapproaches its filial elevated position.

8. A concrete paver comprising a rotatable drum, a hopper therefor, askip for recharging said drum, the said skip comprising a bottom andback extending at an obtuse angle to each other and side walls mergingwith the back and the bottom, two sets of supporting arms pivotallymounted at their inner ends to the paver and positioned eccentricallywith relation to each other, one set of said arms being pivotallyconnected to the bottom of the skip near its mouth and a plate securedto the bottom of the skip extending between the said arms and the secondset of arms being pivotally mounted on the bottom of the skip andrearwardly of the first set of arms and a plate extending between thesearms and secured to the bottom, the inner pivotal point and the lengthof both sets of arms being such that when the skip is raised so the backassumes a vertical position the mouth of the skip will be over thehopper and the plates and one set of arms forming substantially aplatform for supporting the skip against a swaying or tilting movement.

9. In a concrete paver, a rotatable drum having a hopper, a skipcomprising a bottom and back extending at substantially right angles toeach other and open at its forward end having` a double pivotal actionmounted on said paver, a cable for raising said skip, the pivotal actionof the skip and 5 the arrangement of the cable being suoli that the pullon the Cable is tangential at the initial upward movement or" the skip,the

back of the skip travelling through a larger are than the mouth so thatthe material Will not flow from the skip until the mouth is 10 over thehopper.

In testimony lwhereof I affix my signature.
